android - GridView with images from DataBase -

-

i have images in db , put gridview code:

public void setnotes()     {         string[] columns = {notesdbadapt.key_id, notesdbadapt.key_img, notesdbadapt.key_name, notesdbadapt.key_date, notesdbadapt.key_time};         string   table   = notesdbadapt.notes_table;          cursor c = mainnote.mdb.gethandle().query(table, columns, null, null, null, null, null);          startmanagingcursor(c);          simplecursoradapter adapter = new simplecursoradapter(this,                 r.layout.file_dialog_row,                 c,                 new string[] {notesdbadapt.key_img, notesdbadapt.key_name, notesdbadapt.key_date, notesdbadapt.key_time},                 new int[] {r.id.img, r.id.txt, r.id.date, r.id.time});          adapter.setviewbinder(new notesbinder());          gridview.setadapter(adapter); }

all ok, but scrolling slow, jerky. seems information takes db every time. how fix it?

this method deprecated in api level 11. use new cursorloader class loadermanager instead. can perform cursor query on background thread not block application's ui.

Python __call__ special method practical example -

i know __call__ method in class triggered when instance of class called. however, have no idea when can use special method, because 1 can create new method , perform same operation done in __call__ method , instead of calling instance, can call method. i appreciate if gives me practical usage of special method. django forms module uses __call__ method nicely implement consistent api form validation. can write own validator form in django function. def custom_validator(value): #your validation logic django has default built-in validators such email validators, url validators etc., broadly fall under umbrella of regex validators. implement these cleanly, django resorts callable classes (instead of functions). implements default regex validation logic in regexvalidator , extends these classes other validations. class regexvalidator(object): def __call__(self, value): # validation logic class urlvalidator(regexvalidator): def __call__(self, valu...
